The output gate valve has been increased to a height of 10", which means that as long as your sump level is 9" or lower you will not need to worry about fluctuations having an impact on skimming consistency.

The addition of a precision ball valve for airflow control allows the aquarist to fine tune the skimmer`s output.

Unlike most other high performance skimmers in this class, the EV is remarkably silent.

The spray injection system does not generate the sucking noises typical of venturi and Beckett units.

The improved "Twist-Lock" collection cup and cap makes for a secure, flanged connection without the need for set screws or other locking type unions.
